What helps against DDoS attacks better: hardware or cloud solutions?

Question

DDoS Protection

What is the best protection scheme? With iron or without?

Answer 1

Look at the attack. Maybe iptables is enough =)

Answer 2

Any piece of iron implies the presence of communication channels.
There should be many communication channels . In modern realities, attacks with speeds above 100Gbps are a weekly event.
Then simple arithmetic and economics.
